I ran my pack down in Feb. and charged to 100%, Saw no change. Even if I got a few miles back a loss of over 10% in 7 months in not acceptable.

Totally agree but for some of us the last couple of firmware updates added more miles as did the *deep* discharge and full charge. Let us know what the Service Center says.
My pack by the way
Reaout done at a Supercharger a few kilometers from where the car was picked up in Drammen, Norway.Did they at least give you a reason why it was happening such as it being a algorithm problem, charging habits, etc?

No, only that it's a known issue for some early 90D owners and that they are aware and looking for a fix in future firmware. It's very frustrating and common sense says it's not firmware or all the 90s would be having the issue
The first range charge Sunday yielded 282 rated range which is small drop since the 90% charge was consistently 255. However, since that range charge, my 90% charge has be steadily declining -- 254 and now 253. I suspect that the range charge did not precipitate the decline but I hope it stops soon.
Did the firmware updates make a difference for any other 90D owners?

What was it originally and have you recently "balanced" or "recalibrated" your battery by running it down under 20% and then fully charging to 100%?

FYI, today marks the 4th full month of ownership on the P90D. When new at 90% I was at 241. This morning after the charge to 90% I am still at 241 rated miles. I normally now charge up only to about 70% which gets me 188 to 189 rated miles. My daily use is usually under 45 miles however, a few long trips have gotten my odometer up to 5,200 miles give or take. I have Supercharged less than 10 times and only on longer trips. My charge amps is 40 and charge up every morning starting at 5 AM.
So far so good. My battery pack is the 1071394-00-A pack. Have noticed recently, in the warmer weather while on a road trip that the fans run full tilt while at the SuperCharger. In the cooler weather this behavior was not present. Since May I have had Range Mode off.

Was 256 @ 90% originally, which I believe is about 284 @ 100%.
I have not had it balanced or recalibrated. It was down to about 20 miles remaining yesterday.
Lost about 5% range in 9 months.
Charge it to 100% tonight at home while it's only 20 miles or less and see what happens.

Here's another data point for you guys:
P90DL loaner, a little over 5k miles on the odo, shows 269 miles at 100% SoC (new is supposed to be 270). This is with Range Mode ON.
Down to 247 @ 90%. SvC says it is due to the extreme heat in Texas and it should return to normal in a few months. We'll see.
My car is about 10 months old with 5300 miles. Our numbers are very similar 253-254 @90% and 282-283@100%. I balance my battery regularly and I'm curious if you do the same. Before I started doing that I was at 248 @90% and 279 @100%. Some firmware updates along the way also might have helped.
You guys are all lucky .. My P90DL is 225 miles at 90%. It slowly declined by the 2000 mile mark and never recovered. Tesla says its a firmware update but its been since Oct 2015. It has stayed around 225-228 for the last 9 months. I now have 21500 miles and no more degredation. My previous RWD S85 had 62000 miles on it and it had 235 miles at 90%. Has anyone got Tesla to do anything about this?
